kloje experimental gismu

x₁ (set/space) is closed under(/wrt) operator/relation x₂; x₂ has closure in x₁.

Identical to klojere but is a gismu (as it might be considered to be a fairly fundamental concept which is productive).

In notes:

ginlazdze: x₁ is a genetic-familial/'blood' ancestor of x₂ by bond/tie/relation/of degree x₃.
ginlazyseldze: x₁ is a genetic-familial/'blood' descendant of x₂ by bond/tie/relation/of degree x₃.
klojere: x₁ (set/space) is closed under operator/relation x₂; x₂ has closure in x₁.
klojyjoisocnyjoidukni: x₁ is a binary group operator endowing set/space x₂ ; x₂ is the underlying set or the actual structure of a group with operator x₁.
kraune: x₁ (set/family/tree graph) is a crown category/clade/'group'/set formed from and defined by (elements of) set x₂ (nonempty set/family/graph), which have set-wide simultaneous most-recent common ancestor(s) x₃, according to judge/standard/definition/(directed) tree graph/relations x₄.
taknyklojyzilpra: x₁ is the transitive closure (directed graph/set of ordered 2-tuples/space) derived/produced/induced from relation space x₂.
